Metallics JG8HC58234 – Frequently Asked Questions

1) Will a 5/8-11 Grade 8 hex bolt take a standard 5/8 coarse nut?
Yes. The Metallics JG8HC58234 is a 5/8 inch diameter bolt with 11 threads per inch, which is standard UNC coarse thread, so it mates with any 5/8-11 nut or tapped hole. Shank outside diameter runs 0.6170 to 0.6250 inch. For a Grade 8 bolt, pair it with a Grade 8 (or higher) nut so the nut does not become the weak point.
2) What is the difference between a Grade 8 and a Grade 5 hex bolt for heavy equipment work?
Grade is about strength, not size. The Metallics JG8HC58234 is Grade 8: medium carbon steel, heat treated, rated 150,000 psi minimum tensile and 130,000 psi minimum yield, with a Rockwell C33-39 hardness. A Grade 5 bolt in the same 5/8-11 size is softer and lower tensile. Use Grade 8 where the joint sees high clamp load or cyclic loading, which is why these are common in automotive and fleet work. Grade 8 is harder and less forgiving of bending or shock, so it is not an automatic upgrade for every joint.
3) Is the zinc plating on this Grade 8 bolt okay for outdoor or wet locations?
The JG8HC58234 is steel with a zinc finish. Zinc plating gives general corrosion protection for indoor, sheltered, and light outdoor exposure. It is not a stainless or hot dip galvanized bolt, so for constant wet, coastal, or chemical exposure you want a different coating or material.
4) How many bolts come in a jar of Metallics JG8HC58234?
These 5/8-11 x 2-3/4 Grade 8 hex bolts ship 25 to a jar, and the jar packaging is the standard pack for the JG8HC series. Order minimum is 50 each. Other sizes and quantities can be had by request.
5) Does this Metallics bolt qualify for Buy American or ARRA funded projects?
The JG8HC58234 is flagged compliant for both Buy American and ARRA. Country of origin is listed as multiple, so confirm the origin on the lot you receive if your contract requires documented sourcing.
6) What steel is used in the Metallics G8HC Grade 8 hex bolts?
Material standard is AISI 1021 through 1045 medium carbon steel, heat treated to Rockwell C33-39. That is what gets the bolt to its 150,000 psi minimum tensile rating.
